Arthur Mar leads an outstanding research program in inorganic solid-state chemistry at the University of Alberta. He is an international leader recognized for his expertise in the synthesis of extended inorganic solids, especially intermetallic compounds and Zintl phases representing the broad diversity of the periodic table, encompassing rare-earth elements, transition metals, and the less-electronegative p-block elements. Over the past 20 years, Mar has attained a distinguished international reputation in intermetallic chemistry, having published 196 articles (including the only authoritative review on rare-earth bismuthides) and given 88 invited presentations. He has served on the editorial boards of Chemistry of Materials, Journal of Solid State Chemistry, and Acta Crystallographica. In addition to being recognized as an excellent researcher (through the Faculty of Science Research Award at the University of Alberta), he is an outstanding, award-winning teacher who is highly valued for his enthusiastic contributions to chemical education. He was a Professeur invité at the Université de Rennes 1 (2003) and a Distinguished Visiting Scholar at Beijing Normal University (2017).
